I tried the previous post about Wavecenter and Win 7 64 , although I disable the Wctray Startup item (Control Panel) using MSCONFIG I still getting the Blue Screen ,the problem starts when I change the WCConfig (like Dig to Adat , 256 samples or Multichannel setup) since the 64 bits will be a standart in the next year , I think it will be a nice  to create new Drivers for Win 7 32/64 instead of temporary solutions.
